True.
It is the most scratch proof and one of the better corrosion resistive plastic on the market today.
Teflon is a thermoplastic.
It has many useful properties like corrosion resistance, anti-rust action.....etc
This is likely due to the high crystallinity of Teflon as well as the degradation point being very nearly the same as the melting point.
Teflon is the registered trade name of the highly useful plastic material polytetrafluoroethylene (PTFE). PTFE is one of a class of plastics known as fluoropolymers. A polymer is a compound formed by a chemical reaction which combines particles into groups of repeating large molecules.
